Bourassa said he searched the globe to find ink suppliers and even tricked a paper mill overseas into supplying him with paper similar to what is used for the U.S. $20 bill. Bourassa said he would sell the fake bills to organized crime groups.

The RCMP believes that the operation could have produced bills totaling more $250 million.

Bourassa spent a short amount of time in prison in Canada before cutting a deal by revealing where a supply of fake bills was located. He was later set free.

The Secret Service told ABC that Bourassa is not wanted in the United States.

Bourassa said the operation was a thrill.

"It was not supposed to be possible. People like me, we thrive on that," said Bourassa.

Investigators said that fake bills from this operation have been seized in the Northeast and across the country, and that it is possible people have the bills in their wallets right now.
